Not exactly.

I think you need to pass the `-D` switch as well.
Otherwise you can see you have a listing for the actual directories as well, which I *think* might be a problem, and if you take a look at the raw file, the mimetype is moved over.
I have no idea how exactly the mimetype is read, but apparently it's very fragile!

Must be right at the beginning, blah blah blah...

Code:

#!/bin/bash

epub="$(realpath "$1")"
tmp_epub=$(mktemp -d)

unzip "$epub" -d $tmp_epub
pushd $tmp_epub
CONTENT='\t\t<meta property="rendition:layout">pre-paginated</meta>\n\t\t<meta name="original-resolution" content="584x754"/>'
sed -i '/<\/metadata>/i\'"$CONTENT" content.opf
zip -X0 "$epub" mimetype
zip -rDX9 "$epub" * -x mimetype
pushd
rm -rf $tmp_epub

My script doesn't do as much moving around, which is like a total waste of a CPU cycle or two.

And it's "cleaner" to put the extracted files in /tmp - right?

You can also redirect most of the output to /dev/null if you want to make it really professional and distribute it.
